SPECIFICATION forming part of-Letters Patent No.'353,l02, dated November 23,1886.

Application filed July 24, 1886. Serial No. 208,959. (No model.)

To aZZ whom, it may concern: G is a steam-cylinder, open at its upper end Be itknown that I, SAMUEL JACKSON WVEBB, and bolted to the under side of the bed-plate a citizen of the United States, residing at Min- 0. Said plate is provided with an opening den, in theparish ofWebstenand StateofLouiscorresponding in diameter to the opening in 55 5 iana, haveinvented certain new and useful Imthe upper end of the cylinder.

The do hereby declare the following to be a full, upper end of the piston-rod is provided with clear, and exact description of the invention, a central longitudinal opening. such as will enable others skilled in the art to His a movable platen,provided on its under 6o which it appertains to make and usethe same. side with a vertical rod, H, projecting down- My invention is a cotton or hay press; and ward and fittinginto the opening in the upper it consists in the parts which will be hereinend of the piston rod.

The upper endof each post is provided with K is a steam-supply pipe leading into the a horizontally-mounted cog-wheel, B.

Said pipes are provided with suitcogs facing upward, and are also provided able valves to let the steam in and out of the 80 with circumferential spurs or cogs on their cylinder at pleasure. The toggle-arms are peripheries. The two end cogs gear, as shown held together and in their proper positions by in Fig. 2. The posts are mounted in openings pins 1 23 4. p O in the fixed bed plate or sill O.

Said openings are therefore in the nature of safety-valves. When a bale has been compressed, the piston, its rod, the toggle arms, and platen II will gravitate to their lower normal position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cylinder open at one end, said cylinder being provided with a piston and a pistonrod, and also provided with supply and exhaust ports near one end, and exhaust-ports near the open end of the cylinder, whereby when the piston passes above the exhaustports near the open end of the cylinder the steam is automatically exhausted from the cylinder and the pressure of steam removed from the piston, all combined substantially as described.

2. The base-plate 0, provided with corneropenings, revoluble posts A, provided with shoulders and seated in the base-plate openings, the posts being screw-threaded on their upper ends, the movable platen E, provided with screw-threaded openings into which the screw-threaded portions of the posts work, the wheels B, provided on their peripheries and upper outer surfaces with spurs, the shaft D, and wheels D, said spurs being keyed to the shaft, the Wheels B being keyed to the posts, all combined substantially as described, and for the purposes set forth.

3. In a cotton or hay press, the bed-plate 0, provided with lugs F, and having standards or posts mounted thereon a cylinder secured to the under side'of said plate, said cylinders piston extending upward and having the arms J pivoted thereto, the movable platen H, and toggle-arms I I, the arms I being pivoted to the lugs F, the outer ends of the arms I being pivoted to the platen H, the outer ends of the arms J being jointed to the jointed ends of the toggle-arms I I, all combined and operated substantially as described, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL J AOKSON WEBB.
